How do I connect to mySQL through PHP?

Use the following outline to connect and begin querying the mySQL
server from within your PHP scripts. Remember that you cannot connect
to your databases remotely due to security reasons. You can only
connect to them from your local host.

1. Connect to the mySQL Server
Use the following statement to connect to the database server. Substitute
the username, and password for ones you have created in the WebControl
System. MYSQL_CONNECT('localhost','USERNAME','PASSWORD');

2. Select Your Database
Use the following statement to select the database you wish to connect
to. Make sure you substitute the example with your database name.
@mysql_select_db("DATABASENAME");

3. Executing A Query
You are now ready to execute your queries. (Most problems that arise
with your scripts will be due to incorrect permission settings.)
